Quality of care for chronic conditions: identifying specificities of quality aims based on scoping review and Delphi survey

ABSTRACT There is a growing need to implement high quality chronic care to address the global burden of chronic conditions. However, to our knowledge, there have been no systematic attempts to define and specify aims for chronic care quality. To address this gap, we conducted a scoping review and Delphi survey to establish and validate comprehensive specifications. The Institute of Medicine’s (IOM) quality of care definition and aims were used as the foundation. We purposively selected articles from the scientific (n=48) and grey literature (n=26). We sought papers that acknowledged and unpacked the plurality of quality in chronic care and proposed or utilised frameworks, studied their implementation, or investigated at least two IOM quality care aims and implementation. Articles were analysed both deductively and inductively. The findings were validated through a Delphi survey involving 49 international chronic care experts with varied knowledge of, and experience in, low-and-middle-income countries. Considering the natural history of chronic conditions and the journey of a person with a chronic condition, we defined and identified the aims of chronic care quality. The six IOM aims apply with specific meanings. We identified a seventh aim, continuity, which relates to the issue of chronicity. The group endorsed our specifications and several participants gave contextualised interpretations and concrete examples. Chronic conditions pose specific challenges underscoring the relevance of tailoring quality of care aims. The next steps require a tailored definition and specific aims to improve, measure and assure the quality of chronic care.


Background
Chronic conditions, whether non-communicable or infectious, are broadly defined to last 1 year or more and require ongoing medical attention and/or limit activities of daily living [1].These raise particular issues in terms of quality of care: persons with chronic conditions (PwCC) should be offered a seamless journey through time in the healthcare system, across services, providers, levels of care, etc. [2][3][4][5].More fundamentally, although healthcare providers (HCP) are expected to deliver healthcare, having a chronic condition means that PwCC are in-charge of their own health on a day-to-day basis.Daily decisions they make have a huge impact on their own health outcomes and quality of life [6].Thus, chronic care should include disease prevention and medication prescription activities; give focus on disability limitation, rehabilitation [7], and palliative care; and involve, enable and engage the PwCC (and their families) in taking care of the condition, controlling risks and promoting well-being (self-care) [8] considering not only biomedical but also psychosocial aspects to adapt and self-manage in the face of social, physical, and emotional challenges [9,10].It is likewise crucial to acknowledge the reality of multimorbidity.
Although the above are delineated in standards of care for specific chronic conditions and are recognised in different models of chronic care, we did not find any established ready-to-use definition of what would be considered good-quality chronic care [11].Also, while there has been considerable work around a 'global' definition of quality of care and its core 'aims' over the last decades [12][13][14][15], there has been no systematic attempts made yet, to the best of our knowledge, to specify quality aims for chronic care.Having a tailored definition would empower the many and various actors -policy-makers, health financiers/purchasing agencies, healthcare/service providers, healthcare regulators, accreditation agencies, researchers, trainers, PwCC themselves, etc.who are committed to achieve 'good quality chronic care' and/or have the mandate to implement specific quality-enhancing interventions for chronic care.
The main objective of this study was to produce comprehensive specifications of aims of quality of care for chronic conditions.

Conceptual issues
As a starting point, we adopted the definition of quality of care put forward by the Institute of Medicine (IOM) [13][14][15]: Quality of care is the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge, noting that this generic definition needs to be contextualised and the outcomes to be determined.
While we are aware that different documents/ reports have extended or reorganised these, we likewise took the IOM's six aims as our base: effectiveness; efficiency; safety; equity; accessibility, timeliness, affordability; and person-centredness.
With the ideal that quality improvement should focus on the results that matter most to various actors (patients and their families, healthcare providers, regulators, decision makers, etc.), we defined 'aim' as any broad category of importance with intrinsic value, as a desired final outcome that is achieved to denote that care is of good quality.

Methodology
This paper is one of the outputs of a larger study commissioned by the World Health Organization (WHO).The request was to produce a comprehensive conceptualisation of 'quality health services for chronic conditions' that can be used by actors considering interventions to improve health services for chronic conditions, in this case, purchasing arrangements as an instrument for improvement, with a particular attention to policy needs of low-and middle-income countries (LMICs).Here, we concentrate on the specifications of chronic care quality aims.
We reviewed relevant literature and convened international stakeholders of chronic care and quality in a Delphi survey.
We conducted a scoping review following the PRISMA extension guidelines [16] to systematically identify available information on quality of care for chronic conditions, identifying key concepts.We selected works that have acknowledged and unpacked the plurality of quality in chronic care, and which proposed/made use of frameworks or looked into two or more IOM aims of care quality, and studied or demonstrated implementation.The scoping review protocol is available from https://www.itg.be/en/research/research-themes/quality-of-care-forchronic-conditions.

Scientific publications
On 2 February 2022, search for scientific publications was conducted in the PubMed and Science Direct databases using specific search terms: 'chronic condition'/'chronic illness'/'chronic disease'; 'quality of healthcare'; 'innovative care for chronic conditions'; 'chronic care model'; 'quality criteria'; 'quality indicators'; specific chronic conditions considered among top drivers of chronic disease burden [17] ('ischaemic heart disease', 'hypertension' and 'stroke'; 'diabetes mellitus'; 'chronic kidney disease'; 'lung cancer'; 'HIV/ AIDS'; 'chronic obstructive pulmonary disease' and 'bronchial asthma') and additional conditions as suggested by the WHO team ('chronic musculoskeletal conditions'; 'chronic skin disease'); and criteria: written in English or French; publication years 2002-2021; among humans.

Other literature and documents
Search for grey/other literature (policies, circulars, publications not available from scientific search engines) was conducted using similar keywords but including general quality of care documents, and with broader year limitations (1999-2022) in the Google search engine.Additionally, contacts from the WHO and healthcare regulatory agencies, organisations with chronic disease programmes/projects, and various Ministries of Health and/or connected agencies were requested to share any documents they have produced as related to quality of care, specifically for chronic conditions.
Inasmuch as our preliminary searches in the two scientific data bases already had considerable yield (>7,000 each) and wherein ± 40% were duplicates, and that we were able to retrieve rich grey documents, a decision was made to no longer add more data bases to the minimum requisite for scoping reviews.

Literature sifting
Scientific publications were sifted through Rayyan (www.rayyan.ai).This was done systematically by a minimum of two members of the research team.A third researcher resolved any disagreements amongst the two, as needed.Scientific publications were initially screened through the titles.Abstracts of the chosen documents were individually reviewed.Full articles were scrutinised and selected; only documents that are relevant to this study were included in the final selection.
Grey literature and other documents were purposively collected.

Data extraction and analysis
Data retrieval was systematically initiated by at least one of the members of the research team and verified by a different member.We critically analysed the literature.We made use of deductive approaches based on the IOM quality aims, and inductive approaches to identify any additional quality aims; utilising our definition of 'aim' to guide both.Narrative synthesis of retrieved information was done.We brought forward concepts related to the aims of good-quality chronic care.We note that quality aims were not always explicitly stated.We then deduced the aims based on our critical analysis of the text using the IOM aims as our base.We also identified any quality aim not included in the IOM proposition.Furthermore, the analysis was reflective and iterative, going back to the literature as we identified additional concepts.

Delphi survey
We invited 52 respondents representing various stakeholders of chronic care and quality (including PwCC and their carers) from all over the world.We prepared a list of 'mid'-to 'advanced' level chronic care experts, gleaned through our own professional networks, references from colleagues or other known experts, relevant publications in peer-reviewed journals or the websites of relevant organisations, and from recommendations by different organisations (e.g.NCD Alliance, Global Alliance on Chronic Diseases), and supplemented by the WHO Team.A concern was to secure, to the extent possible, representation across genders, types of expertise, and settings of activities/experience (with focus on low-and middle-over high-income settings), covering the six WHO regions.We conducted two rounds of the Delphi survey via an online application, Mesydel (https://mesydel.com/en).The first step was to arrive at an agreement over our scoping review findings that build towards the chronic care quality framework, and to propose financing mechanisms to improve the quality of chronic care.Based on firstround results, the second round was conducted to fine-tune purchasing arrangements.Findings contributing to the chronic care quality framework beyond the definition and aims of quality chronic care and including those on financing mechanisms will be presented in separate papers.For this paper, we concentrated on Round 1 results relating to our proposed chronic care quality aims.The respondents provided a rich justification for why specific chronic care quality aims should be included in the free-flow component of the survey.We synthesised and critically analysed the responses, reflecting on our scoping review findings and contrasting and comparing all information collected.

Results
We retrieved 15,215 scientific articles and retained 48  (Figure 1).The study designs were as follows: 17 reviews; 12 implementation research (quality improvement and/or model implementation); nine cross-sectional/surveys; three randomised controlled trials; three qualitative and mixed methods; two case studies; one qualitative study; and one position statement.Eighteen are specific for certain chronic conditions (diabetes = 5, cardiovascular diseases including hypertension and stroke = 5; HIV/AIDS = 2; chronic obstructive pulmonary disease = 2; chronic kidney disease = 2; osteoarthritis = 1; and cancer = 1).Some targeted specific groups (elderly = 5, children = 1, female = 1, informal caregiver = 1).Forty-six propose and implement or demonstrate implementations of various models of quality of care, mostly in highincome countries (n = 31), five in LMICs; South Africa = 3, Haiti = 1, not specified = 1), and the rest (n = 10) said to be global/international.Majority (n = 46) fit and consolidate the IOM definition of quality and two or more of the IOM care quality aims.A couple [46,47] consider Donabedian's [66] elements of quality in healthcare.
During data extraction, we noted that the scientific papers usually concentrate on a particular stage in what we deem to be the 'journey' of a person through healthcare, considering the natural history of (most) chronic conditions (e.g.risk-prevention/-control, follow-up, rehabilitation, etc.).We thus went back to our selection to consciously extract additional information that would expound on the relevance of various stages in a continuum of care relevant to the identified aims.We will discuss the concept of the PwCC journey in a related paper.
Tables 1 and 2 provide overviews of the scientific articles and grey literature and chronic care quality aims identified.

Delphi survey
Forty-nine of the 52 invited stakeholders (94%) consented and participated in the Delphi survey.Table 3 provides demographic and pertinent characteristics.

Specifying aims for good-quality chronic care
For quality of care for chronic conditions, we noted that the six aims as proposed by the IOM: effectiveness; efficiency; safety; equitability; accessibility, timeliness, and affordability; and person-centredness also apply.Additionally, we identified a seventh aim, continuity of care.There was consensus among the Delphi participants on our propositions; they also provided reasons why each proposed aim should be included.One panellist recommended giving enough attention to integration to organise achieving the aims.
A respondent highlighted efficiency and related this to affordability: Efficiency combines effectiveness at a more appropriate cost; this can already solve many access issues, namely financial access issues.
Safety is defined by the IOM as avoiding harm to PwCC from the care that is intended to help them [14,78].The WHO [12] specifies this as 'patient safety'.However, the grey literature from the Philippines [87] gives a broader goal to provide patients, staff, and other individuals within the health facility a safe environment.This quality aim appeared in only three of the scientific literature we reviewed [29,39,52] and in 10 of the grey literature [12,14,15,70,[76][77][78]80,83,87].
A respondent indicated that safety can be complex and affected by the context.
. . .given the context in which the implementation takes place, with low or middle (income country) organizational conditions lacking material and sometimes motivation from the workforce, safety can be a problem, especially in remote areas. . .Equity, expressed as ensuring that all PwCCs can access good-quality healthcare that is responsive to their needs regardless of personal characteristics [12] were identified in four of the scientific articles [23,29,40,43] and four other grey literature [3,14,15,70].
A respondent indicated that: Inequity has always been a major challenge, not only due to socioeconomic classes, but also due to clientelism practiced by politicians, including health ministers, whereby 'connected' persons had better access to healthcare.
Respondents spoke about geographic and financial accessibility and timeliness, and linked accessibility to equity.
'The biggest challenge is access to care for chronic diseases, such as diabetes, for all patients wherever they are, given the geographical complexity'.(of specific countries) . . .there is a vast gap between the theoretical coverage of the social health insurance system and the actual coverage, which generates disparities in access to health care in general, particularly for people suffering from chronic conditions.This mainly affects people in rural areas and low-income communes in urban settings.
Patients should (be able to) access quality chronic care when they need, without any barrier.
In the Delphi, respondents connected person-centredness to access and talked about 'empowerment'.

Within a context of rapidly escalating co-and multimorbidities, it is critical (to) reflect (on) mechanisms which create access to care for the 'person' and not the 'disease or conditions'. I would put a premium on empowering patients to be able to do self-care, particularly for interventions that have been proven to be effective.
We identified a seventh aim, 'continuity of care', which is particularly important for people who require regular, consistent healthcare services for a long period of time.Continuity is among the recommendations by the Institute of Medicine in 2001 [14] (Care based on continuous healing relationships).The WHO's ICCC Framework [73] extensively discusses continuity across time and care settings.Continuity is the focus of one of our grey literature (Jackson et al. [85]), where it is defined as the degree to which a series of discrete health events is experienced as coherent and connected, and consistent with the patient's healthcare needs and personal context.It includes the capacity to monitor and respond to change, support self-management goals, and link to community resources [37].It also includes follow-up and tracing of lost-to-follow-up [23,57].Three sub-dimensions are given by Jackson et al. [85], which we utilised as a further basis for inductive and deductive analysis: [i] Relational/relationship continuity, defined as a trusting relationship with one or more HCP who help bridge healthcare episodes over time.
[ii] Informational continuity, where health information as well as other relevant information about the PwCC (their values, preferences, contexts) are shared.
(i.e., shared medical records) [iii] Management continuity, where patient-related information regarding their case management is communicated to different relevant HCP.
Respondents placed value on continuity as a quality aim, especially for chronic care.
. . .continuity of care is probably the major issue regarding chronic diseases . . .A lack of continuity of care is currently one of the main reasons patients who access the system fall through the cracks.
Continuum of care is vital for NCDs. . .Based on our definition, 'Integration' does not qualify as an aim.We note that one grey literature refers to it as a measurable characteristic of quality of care (i.e.considered as an aim) [12] and another as a necessary characteristic of (people-centred) health care [84].One grey literature focuses on integration, where it is described as an action or a process [4].Thirteen scientific literature [24,[39][40][41]43,44,46,49,51,[61][62][63]65] we reviewed mention it as instrumental to improving quality of care for chronic conditions.
One of the Delphi respondents indicated: a key thing is the principle (the 'what'), and that is the principle of integrated chronic care.Right now, we have reactive, short-term care . . .changing that mindset is priority.

Another stated that
for improved care on chronic conditions we need to achieve . . .delivery within integrated care pathways spanning across (the) care sector and being organised around the patient . . .

Discussion
Chronic conditions raise particular issues in healthcare because they last for a long time and, more often, throughout the lifetime of the person.Another consideration is the natural history of chronic conditions and the 'journey' of a PwCC through time, traversing the natural history.To respond to these, healthcare services should encompass risk-and disease-prevention, clinical management of the condition and any complications and/or multi-morbidity, rehabilitation and/or community re-integration, palliative/end-oflife care, and considering the psychosocial aspects of the PwCC.Additionally, clinical/biomedical control of chronic conditions is not static.PwCCs experience episodes of good and poor control of the condition at different moments throughout their lifetime.Control of the condition can be affected by many factors such as continued exposure to risks and determinants, other health problems, e.g.infections, psychological issues (anxiety, depression, etc.), co-morbidity, suboptimal clinical management by either the healthcare system or by the PwCC/informal caregivers themselves, as well as social factors (e.g.lack of social support).These redound to specific healthcare needs and corresponding services and support the view to reflect on how the quality of such healthcare would be defined.
We have formulated a definition and determined quality aims paying attention to the specificities of chronic conditions and their care.We define quality of chronic care as the degree to which healthcare services for individuals and populations with chronic conditions -including provision of education and support to adapt and self-manage in the face of social, physical, and emotional challenges -which are consistent with current professional knowledge and increase the likelihood of desired health outcomes and biopsychosocial well-being.This complements our chronic care quality aims, wherein achievement of each is influenced by and would contribute to realisation of our definition.
Regarding the aims, we noted from the literature review and the Delphi survey that most of the IOM care quality aims -namely effectiveness, safety, equity, person-centredness, and accessibility -take on new, additional meanings specific for chronic care.
Further to 'effectiveness' as a chronic care quality aim is the consideration that people develop chronic condition(s) due to exposure to various risk factors and social determinants of health [18,20].These would also still affect the person even if they already have a chronic condition, and increase the propensity of having poor clinical control, emergence of complications and/or development of other morbidities [30].Thus, effective health services to prevent and control risks, e.g.healthy lifestyle promotion, smoking cessation counselling, etc., should be provided to the general population and the PwCCs (in addition to their effective case management).This was also pointed out by our Delphi survey respondents.Logically, failure to provide effective services to prevent and control risks would increase the number of PwCCs and could give rise to multi-morbidity.Compounding this with failure to deliver effective chronic care would further increase the burden of chronic conditions.However, an understanding of the responsibilities of the health system needs to be clarified.Addressing the various risks and social determinants themselves, e.g.air pollution control, increasing access to healthy food, regulation of sales of unhealthy products, food (re)formulations, tobacco and alcohol taxations, etc., would need actions beyond the scope of the health system, even if the health system may initiate multi-sectoral policies and actions [88].Furthermore, effectiveness should not be limited to chronic care provision alone.PwCC are often immunocompromised, making them susceptible to various infections.Responsive health systems should thus have the capacity and capability to effectively provide care for both chronic conditions and acute infections and support the psychosocial needs of PwCC.
With the ballooning burden of chronic conditions and higher demands for chronic care, efficiency becomes a dire necessity across all settings.Whilst efficiency can be looked at individual level (best use of own resources), it has more relevance as an aim at collective level.From the societal perspective, efficiency ensures that what is not wasted on one person is available for the other who truly needs it.Efficiency, especially of chronic care, is one of the main aims of many recent health system reforms, which are, however, being implemented mainly in high-income countries.
We echo one of our Delphi respondents that safety is indeed complex and largely depends on the context.Moving from concentrating only on patient safety, we favour the more extensive safety aim presented in the PhilHealth Bench Book [87], which includes measures for both patients and (healthcare) staff and providing a safe environment for healthcare delivery.In addition, effects of chronic care delivery on the environment should also be considered; for instance, cytostatic drugs excreted by cancer patients finding their way to wastewater and affecting biodiversity of freshwater organisms.Concrete examples of broader safety include: having appropriate facility design, e.g. to accommodate people with disabilities; prevention of adverse care incidents, e.g.druginduced hypoglycaemia, drug-drug interactions in cases of polypharmacy (especially among PwCC with comorbidities/multi-morbidity); provision of equipment and devices needed to deliver safe care, e.g.personal protective equipment; proper waste handling, including proper disposal of sharps used by both the staff and PwCC, appropriate wastewater treatment, etc.While safety was the least studied quality aim among the papers we reviewed, its importance in chronic care and its wider application including effects on global environmental changes cannot and should not be discounted.
Equity is a cross-cutting consideration in our societies.It can be assessed over any metric of interest and consists of a normative judgement on the distribution within a group of persons; it is usually not an aim at individual level, but at collective level.For instance, there can be equity considerations on how households financially contribute to the general funding of the health system, with different views on what would be fair.Health systems performance and UHC literature has put equity as a core consideration [70].Akin to equity in healthcare in general and as defined by the IOM, we propose to refer to equity as the aim capturing distributional considerations related to quality of chronic care.The first concern should be that care does not vary in quality (effectiveness, safety, timeliness, person-centredness, etc.) because of personal characteristics such as gender [64], ethnicity, socioeconomic status, disabilities, etc. [29].Such fairness redounds in health promotion and all levels of prevention of chronic conditions, especially in LMICs where exposure to risks and social determinants, and the prevalence of most chronic conditions have been documented to be higher among lower socio-economic groups, and where more inequities have also been noted (e.g. between sexes, ethnicity).
As regards individual PwCC, we deduce, and view, person-centredness to be more holistic and more allencompassing than what is defined by both IOM and WHO.To deliver person-centred chronic care, what should be strived for should go beyond the 'patient is a person' concept.The recognition and acceptance should be framed as follows: the 'person is sometimes a patient' and the 'patient is always a person'.The biomedical, psychological and social aspects of PwCC need to be considered [10,12,50,52].They should be 'activated'/stimulated to become experts of their condition and should be guided to accept and recognise that their chronic condition is only one of the facets of their whole life.Emphasis is given on their human agency and their capacity to make their own decisions, set goals, take actions, and sustain efforts.Therefore, beyond empowerment/enablement for self-management, there should be engagement of the PwCC for collaborative care and involvement in applicable committees to improve chronic care quality [25,42,71].Such engagement extends to their family, their informal caregivers and the community [23,39,49,63].A goal would be that PwCCs will be able to 'juggle' the different facets of their life effectively to maximise their physical/biological, psychological and social well-being, and are supported accordingly.
Accessibility, affordability, and timeliness are mainly instrumental to other aims.However, they also have intrinsic value.Following Levesque et al.'s [89] proposition, we further dissect this aim as applied to chronic care: a. Geographic accessibility -to help enable PwCC to consult and follow-up regularly without having to travel a great distance and/or encountering too many difficulties in travelling and/or losing much time for travel and/or incurring unreasonable transportation expenses [29,61] The effects of achieving the different sub-dimensions of the above aim are many-fold: improving chronic care delivery and utilisation of healthcare services, contributing to improved adherence of PwCC, improving (clinical) outcomes, etc. Achieving this aim would directly contribute to the achievement of good-quality chronic care, as we defined.
The intrinsic value of our seventh aim, continuity, is how it acknowledges that time and its continuity (past, present and future) matter for the PwCC.It addresses chronicity, which can be discerned from the three subdimensions proposed by Jackson et al. [85].
[i] Relational/relationship continuity, as establishing rapport and trust between the HCP and the PwCC would be crucial to build a lasting relationship, help ensure regular follow-up, and more likely promote (long-term) adherence [29,39,51,52].
Informational and management continuity go hand-in-hand, where relevant information about the PwCC (informational continuity) as well as care management plans (management continuity) would be co-developed and shared with relevant care providers (including informal caregivers) and the PwCC and would follow the PwCC in their journey through healthcare.
A thorny issue is the status of 'integration', for which multiple definitions have been given [4].Certainly, poor and insufficient integration of service delivery is a major issue in many countries given the current state of their health systems.This observation, shared across settings including in high-income countries, probably motivated the decision to elevate integration as an aim in another quality of care framework [12].However, we propose to distinguish the conceptual undertaking of identifying the aims of quality of care from policy agendas inspired by current situations.From a conceptual perspective, our assessment is that integration does not meet the intrinsic value criterion of an aim nor is it a directional metric (for which any progress is valuable).It, however, plays a special role in care quality.Goodquality chronic care requires integration.However, integration is not the goal per se (in contrast to the seven dimensions of quality of chronic care), but is a means: it is instrumental in achieving quality aims.The process of integration or the action of integrating healthcare organisations and/or its people and/or its services and/or its functions -to deliver integrated care -can help achieve, more particularly, effectiveness, efficiency, person-centeredness, and continuity.To a lesser extent, it can also contribute towards accessibility and safety.Conceptually, integration is desirable, but only to the extent that it positively serves quality aims.Empirically, we acknowledge that it should be a top priority in all health systems; a way to organise actions to improve quality of (chronic) care.Our proposition to elevate integration as an organising principle to achieve the aims of quality chronic care will be discussed in a separate paper.

Limitations
Available literature on quality of (chronic) care mostly documents experiences in high-income countries, this was also the case in our scoping review.We mitigated this limitation by purposively selecting Delphi participants with expertise and experiences on chronic care in LMICs.
We also noted that specific aims got more attention over others (for instance, effectiveness was the focus of almost all of the scientific literature we reviewed, while less than 10 were on equity, safety).While this may be an unintended effect of our literature search, we noted that effectiveness is usually the de facto aim that is studied because of the value placed on desired clinical outcomes as the endpoint.However, this does not warrant inattention to the other aims.The inclusion of grey literature, most of which tackled all aims, made sure that we have a broad understanding even of the least studied aims in the scientific literature.
We have adopted the view that 'aims' should be intrinsically valuable.It is important to understand that this does not mean that non-included aims are irrelevant.
Although we introduced the PwCC journey and the relevance of the various stages in a continuum of care relevant to the identified aims, we are aware that we did not have room to expound more on this concept.We will discuss this in more detail in a separate paper presenting our conceptual quality of chronic care framework.

Conclusions
With this paper, we have moved from a generic understanding of quality of care to one tailored to chronic conditions.Beyond aims, we have also determined the scope of attention, one which values a comprehensive offer of healthcare services, addresses risks and social determinants of health, ensures biopsychosocial well-being of PwCC, and gives importance to quality of care characteristics relevant to the PwCC and their families, to the community, and to the health system.
Our scoping review shows that some aims have received more attention than others.However, limited attention should not be interpreted as an acceptable reason for neglect.Our Delphi survey respondents underlined the value of each of the seven chronic care quality aims that we identified, especially as applied to low-income settings.

Implications for policy & further research
Our team used these aims to create a chronic care quality framework, and then, via the Delphi survey, mobilised the international panel of experts to apply the said framework for possible purchasing arrangements to improve quality of chronic care in LMICs.The chronic care quality framework and the Delphi survey results on purchasing arrangements will be presented separately.These are all components of the larger programme of work implemented by WHO, which focuses on purchasing arrangements as an instrument to improve health services for chronic conditions.It is expected that member states will take inspiration from this programme of work, in their efforts to improve care for chronic conditions.Actors active in chronic care may also be inspired by our specifications, in designing good-quality chronic care services or working on improvement strategies thereto.
The output we presented in this paper is conceptual.Operationalisation for systematic improvements in quality of chronic care can be the next step, among others, to demonstrate the usefulness, or not, of each of these specified chronic care quality aims, in specific settings.
Our paper may also inspire other calibrations and validation of the definition and aims of quality of care for other health problems.We hypothesise that they could be valuable preparatory steps among those committed to improve quality of care for specific health conditions.Having a tailored understanding of quality of care will only make quality improvement interventions better.
